TCPDUMP Command/Tool
- Tcpdump command is a famous network packet analysing tool that is used to display TCP\IP & other network packets being transmitted over the network.
- That are attached to the system on which tcpdump has been installed.
- Tcpdump is a most powerful and widely used command-line packets sniffer or package analyzer tool which is used to capture or filter TCP/IP packets that received or transferred over a network on a specific interface.
- It is available under most of the Linux/Unix based operating systems. tcpdump also gives us a option to save captured packets in a file for future analysis.
- It saves the file in a pcap format, that can be viewed by tcpdump command or a open source GUI based tool called Wireshark (Network Protocol Analyzier) that reads tcpdump pcap format files.
- Tcpdump command can read the contents from a network interface or from a previously created packet file or we can also write the packets to a file to be used for later. One must use the tcpdump command as root or as a user with sudo privileges.
Really informative post about the TCPDUMP tool! I like how clearly you explained its ability to capture and filter packets, and also the part about saving traffic into .pcap files for later analysis with Wireshark. That’s such a practical feature for students and professionals learning network troubleshooting.For readers who enjoy experimenting with tools in other fields, projects like how to change textures in minecraft show how much fun it can be to tweak and analyze systems whether it is packets on a network or graphics inside a game. Both require curiosity and careful observation!
